SPHK1 encodes sphingosine kinase 1 (SphK1), a lipid kinase that phosphorylates sphingosine to generate sphingosine-1-phosphate (S1P), a bioactive sphingolipid that influences cell survival, proliferation, migration, and inflammatory signaling. By shifting the balance between pro-apoptotic ceramide/sphingosine and pro-survival S1P, SphK1 participates in the sphingolipid rheostat and integrates inputs from growth factor and cytokine pathways. S1P produced by SphK1 can act intracellularly and through S1P receptors to modulate downstream programs including MAPK/ERK, PI3K/AKT, NF-κB, and angiogenic responses. Dysregulated SPHK1/S1P signaling has been linked to oncogenic phenotypes, fibrosis, and immune-mediated inflammation, making it a widely studied node in disease-relevant signaling networks.
SphK1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SPHK1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SPHK1. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt SPHK1 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of SPHK1-disrupted clones.
